Review of green supply chain processes
(IFAC-PapersOnLine, 2015)
In the last few decades, environmental concerns of manufacturing operations have motivated the organisations to implement green principles in different processes of the supply chain. In this paper, literature in green ...
An analytical modeling framework for determining the optimal table mix in restaurants
(IFAC-PapersOnLine, 2015)
We present a queuing theory based optimization model for determining the optimal table mix in a restaurant. The optimal table mix problem is formulated for an allotment policy in which the largest available group is allotted ...
A cooperative quay crane-based stochastic model to estimate vessel handling time
(Springer, 2017)
Having a good estimate of a vessel’s handling time is essential for planning and scheduling container terminal resources, such as berth positions, quay cranes (QCs) and transport vehicles. However, estimating the expected ...
Solving semi-open queuing networks with time-varying arrivals: an application in container terminal landside operations
(Elsevier, 2018-06-16)
Semi-open queuing networks (SOQNs) are widely applied to measure the performance of manufacturing, logistics, communications, restaurant, and health care systems. Many of these systems observe variability in the customer ...
Sea container terminals: new technologies and OR models
(Palgrave Macmillan, 2015)
Owing to a rapid growth in world trade and a large increase in the flow of containerized goods, sea container terminals play a vital role in globe-spanning supply chains. Container terminals should be able to handle large ...
Inventory allocation in robotic mobile fulfillment systems
(Taylor and Francis, 2020)
A Robotic Mobile Fulfillment System is a recently developed automated, parts-to-picker material handling system. Robots can move storage shelves, also known as inventory pods, between the storage area and the workstations ...
A stochastic model for interterminal container transportation
(INFORMS, 2017)
We propose a novel semiopen queuing network (SOQN) model for the interterminal transportation (ITT) problem where multiple container terminals use a common
fleet of vehicles (automated lift vehicles, automated guided ...
Worth the wait? How restaurant waiting time influences customer behavior and revenue
(ScienceDirect, 2018)
In many service industries, customers have to wait for service. When customers have a choice, this waiting may influence their service experience, sojourn time, and ultimately spending, reneging, and return behavior. Not ...
Performance analysis of batching decisions in waveless order release environments for e-commerce stock-to-picker order fulfillment
(International Transactions in Operational Research, 2020-12-14)
Warehouse automation is increasingly adopted to manage throughput fluctuations in e-commerce order fulfillment. This work develops queuing network models and solution methodologies for performance analysis of a stock-to-picker ...
Stochastic modeling of parallel process flows in intra-logistics systems: applications in container terminals and compact storage systems
(European Journal of Operational Research, 2020-08-08)
Many intra-logistics systems, such as automated container terminals, distribution warehouses, and cross-docks, observe parallel process flows, which involve simultaneous (parallel) operations of independent resources while ...
